Description
We have studied an "isoelectronic" Fe-site doping with Cr and Ni in Ba(Fe1–xCrx/2Nix/2)2As2 system. With increasing x, the antiferromagnetic SDW in the parent compound is suppressed quickly. Spin glass state emerges in the range of 0.1 ≤ x < 0.2. The spin glass state evolves into cluster glass with further doping, and finally becomes ferromagnetism at x = 1.0. No superconductivity was observed down to 0.5 K. The electronic phase diagram is established, and the underlying physics is discussed.
